Compatibilized resin-cement composite compositions

ABSTRACT

Various embodiments disclosed relate to compatibilized resin-cement composite compositions and methods of using the same. In various embodiments, the present invention provides a method of treating a subterranean formation that includes placing in the subterranean formation a resin-cement composite composition. The resin-cement composite composition includes a resin, a cement, and a substituted or unsubstituted poly(alkylamine) compatibilizer.

BACKGROUND

Cement and resin are both used as separate and discrete systems in the oilfield. In some cases, it is desirable to mix these systems together to form a composite material in a mixture that exhibits advantageous qualities from both systems. Unfortunately, cement and resin are generally incompatible with one another and have a tendency to phase-separate after being mixed, an effect that is more pronounced at higher concentrations.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to certain embodiments of the disclosed subject matter, examples of which are illustrated in part in the accompanying drawings. While the disclosed subject matter will be described in conjunction with the enumerated claims, it will be understood that the exemplified subject matter is not intended to limit the claims to the disclosed subject matter.

Values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For example, a range of “about 0.1% to about 5%” or “about 0.1% to 5%” should be interpreted to include not just about 0.1% to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range. The statement “about X to Y” has the same meaning as “about X to about Y,” unless indicated otherwise. Likewise, the statement “about X, Y, or about Z” has the same meaning as “about X, about Y, or about Z,” unless indicated otherwise.

In this document, the terms “a,” “an,” or “the” are used to include one or more than one unless the context clearly dictates otherwise. The term “or” is used to refer to a nonexclusive “or” unless otherwise indicated. The statement “at least one of A and B” has the same meaning as “A, B, or A and B.” In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation. Any use of section headings is intended to aid reading of the document and is not to be interpreted as limiting; information that is relevant to a section heading may occur within or outside of that particular section.

In the methods of manufacturing described herein, the acts can be carried out in any order without departing from the principles of the invention, except when a temporal or operational sequence is explicitly recited. Furthermore, specified acts can be carried out concurrently unless explicit claim language recites that they be carried out separately. For example, a claimed act of doing X and a claimed act of doing Y can be conducted simultaneously within a single operation, and the resulting process will fall within the literal scope of the claimed process.

Selected substituents within the compounds described herein are present to a recursive degree. In this context, “recursive substituent” means that a substituent may recite another instance of itself or of another substituent that itself recites the first substituent. Recursive substituents are an intended aspect of the disclosed subject matter. Because of the recursive nature of such substituents, theoretically, a large number may be present in any given claim. One of ordinary skill in the art of organic chemistry understands that the total number of such substituents is reasonably limited by the desired properties of the compound intended. Such properties include, by way of example and not limitation, physical properties such as molecular weight, solubility, and practical properties such as ease of synthesis. Recursive substituents can call back on themselves any suitable number of times, such as about 1 time, about 2 times, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 30, 50, 100, 200, 300, 400, 500, 750, 1000, 1500, 2000, 3000, 4000, 5000, 10,000, 15,000, 20,000, 30,000, 50,000, 100,000, 200,000, 500,000, 750,000, or about 1,000,000 times or more.

A drilling fluid, also known as a drilling mud or simply “mud,” is a specially designed fluid that is circulated through a wellbore as the wellbore is being drilled to facilitate the drilling operation. The drilling fluid can be water-based or oil-based. The drilling fluid can carry cuttings up from beneath and around the bit, transport them up the annulus, and allow their separation. Also, a drilling fluid can cool and lubricate the drill bit as well as reduce friction between the drill string and the sides of the hole. The drilling fluid aids in support of the drill pipe and drill bit, and provides a hydrostatic head to maintain the integrity of the wellbore walls and prevent well blowouts. Specific drilling fluid systems can be selected to optimize a drilling operation in accordance with the characteristics of a particular geological formation. The drilling fluid can be formulated to prevent unwanted influxes of formation fluids from permeable rocks and also to form a thin, low permeability filter cake that temporarily seals pores, other openings, and formations penetrated by the bit. In water-based drilling fluids, solid particles are suspended in a water or brine solution containing other components. Oils or other non-aqueous liquids can be emulsified in the water or brine or at least partially solubilized (for less hydrophobic non-aqueous liquids), but water is the continuous phase. A drilling fluid can be present in the resin-cement composite composition or a mixture including the same in any suitable amount, such as about 1 wt % or less, about 2 wt %, 3, 4, 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 85, 90, 95, 96, 97, 98, 99, 99.9, 99.99, or about 99.999 wt % or more.

A water-based drilling fluid in embodiments of the present invention can be any suitable water-based drilling fluid. In various embodiments, the drilling fluid can include at least one of water (fresh or brine), a salt (e.g., calcium chloride, sodium chloride, potassium chloride, magnesium chloride, calcium bromide, sodium bromide, potassium bromide, calcium nitrate, sodium formate, potassium formate, cesium formate), aqueous base (e.g., sodium hydroxide or potassium hydroxide), alcohol or polyol, cellulose, starches, alkalinity control agents, density control agents such as a density modifier (e.g., barium sulfate), surfactants (e.g., betaines, alkali metal alkylene acetates, sultaines, ether carboxylates), emulsifiers, dispersants, polymeric stabilizers, crosslinking agents, polyacrylamides, polymers or combinations of polymers, antioxidants, heat stabilizers, foam control agents, solvents, diluents, plasticizers, filler or inorganic particles (e.g., silica), pigments, dyes, precipitating agents (e.g., silicates or aluminum complexes), and rheology modifiers such as thickeners or viscosifiers (e.g., xanthan gum). Any ingredient listed in this paragraph can be either present or not present in the mixture.

An oil-based drilling fluid or mud in embodiments of the present invention can be any suitable oil-based drilling fluid. In various embodiments the drilling fluid can include at least one of an oil-based fluid (or synthetic fluid), saline, aqueous solution, emulsifiers, other agents or additives for suspension control, weight or density control, oil-wetting agents, fluid loss or filtration control agents, and rheology control agents. An oil-based or invert emulsion-based drilling fluid can include between about 10:90 to about 95:5, or about 50:50 to about 95:5, by volume of oil phase to water phase. A substantially all oil mud includes about 100% liquid phase oil by volume (e.g., substantially no internal aqueous phase).

A pill is a relatively small quantity (e.g., less than about 500 bbl, or less than about 200 bbl) of drilling fluid used to accomplish a specific task that the regular drilling fluid cannot perform. For example, a pill can be a high-viscosity pill to, for example, help lift cuttings out of a vertical wellbore. In another example, a pill can be a freshwater pill to, for example, dissolve a salt formation. Another example is a pipe-freeing pill to, for example, destroy filter cake and relieve differential sticking forces. In another example, a pill is a lost circulation material pill to, for example, plug a thief zone. A pill can include any component described herein as a component of a drilling fluid.

In various embodiments, the resin-cement composite composition or mixture including the same can include a proppant, a resin-coated proppant, an encapsulated resin, or a combination thereof. A proppant is a material that keeps an induced hydraulic fracture at least partially open during or after a fracturing treatment. Proppants can be transported into the subterranean formation (e.g., downhole) to the fracture using fluid, such as fracturing fluid or another fluid. A higher-viscosity fluid can more effectively transport proppants to a desired location in a fracture, especially larger proppants, by more effectively keeping proppants in a suspended state within the fluid. Examples of proppants can include sand, gravel, glass beads, polymer beads, ground products from shells and seeds such as walnut hulls, and manmade materials such as ceramic proppant, bauxite, tetrafluoroethylene materials (e.g., TEFLON™ polytetrafluoroethylene), fruit pit materials, processed wood, composite particulates prepared from a binder and fine grade particulates such as silica, alumina, fumed silica, carbon black, graphite, mica, titanium dioxide, meta-silicate, calcium silicate, kaolin, talc, zirconia, boron, fly ash, hollow glass microspheres, and solid glass, or mixtures thereof. In some embodiments, the proppant can have an average particle size, wherein particle size is the largest dimension of a particle, of about 0.001 mm to about 3 mm, about 0.15 mm to about 2.5 mm, about 0.25 mm to about 0.43 mm, about 0.43 mm to about 0.85 mm, about 0.85 mm to about 1.18 mm, about 1.18 mm to about 1.70 mm, or about 1.70 to about 2.36 mm. In some embodiments, the proppant can have a distribution of particle sizes clustering around multiple averages, such as one, two, three, or four different average particle sizes. The resin-cement composite composition or mixture can include any suitable amount of proppant, such as about 0.01 wt % to about 99.99 wt %, about 0.1 wt % to about 80 wt %, about 10 wt % to about 60 wt %, or about 0.01 wt % or less, or about 0.1 wt %, 1, 2, 3, 4, 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 85, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, about 99.9 wt %, or about 99.99 wt % or more.

System or Apparatus.

In various embodiments, the present invention provides a system. The system can be any suitable system that can use or that can be generated by use of an embodiment of the resin-cement composite composition described herein in a subterranean formation, or that can perform or be generated by performance of a method for using the resin-cement composite composition described herein. The system can include a composition including a resin, a cement, and a substituted or unsubstituted poly(alkylamine) compatibilizer. The system can also include a subterranean formation including the composition therein. In some embodiments, the composition in the system can also include a downhole fluid, or the system can include a mixture of the composition and downhole fluid. In some embodiments, the system can include a tubular, and a pump configured to pump the composition into the subterranean formation through the tubular.

Various embodiments provide systems and apparatus configured for delivering the resin-cement composite composition described herein to a subterranean location and for using the composition therein, such as for a cementing operation, a repair operation, a consolidation operation, or a fracturing operation. In various embodiments, the system or apparatus can include a pump fluidly coupled to a tubular (e.g., any suitable type of oilfield pipe, such as pipeline, drill pipe, production tubing, and the like), with the tubular containing a resin-cement composite composition including the resin, cement, and substituted or unsubstituted poly(alkylamine) compatibilizer described herein.

In some embodiments, the system can include a drill string disposed in a wellbore, with the drill string including a drill bit at a downhole end of the drill string. The system can also include an annulus between the drill string and the wellbore. The system can also include a pump configured to circulate the resin-cement composite composition through the drill string, through the drill bit, and back above-surface through the annulus. In some embodiments, the system can include a fluid processing unit configured to process the resin-cement composite composition exiting the annulus to generate a cleaned drilling fluid for recirculation through the wellbore.

The pump can be a high pressure pump in some embodiments. As used herein, the term “high pressure pump” will refer to a pump that is capable of delivering a fluid to a subterranean formation (e.g., downhole) at a pressure of about 1000 psi or greater. A high pressure pump can be used when it is desired to introduce the resin-cement composite composition to a subterranean formation at or above a fracture gradient of the subterranean formation, but it can also be used in cases where fracturing is not desired. In some embodiments, the high pressure pump can be capable of fluidly conveying particulate matter, such as proppant particulates, into the subterranean formation. Suitable high pressure pumps will be known to one having ordinary skill in the art and can include floating piston pumps and positive displacement pumps.

In other embodiments, the pump can be a low pressure pump. As used herein, the term “low pressure pump” will refer to a pump that operates at a pressure of about 1000 psi or less. In some embodiments, a low pressure pump can be fluidly coupled to a high pressure pump that is fluidly coupled to the tubular. That is, in such embodiments, the low pressure pump can be configured to convey the resin-cement composite composition to the high pressure pump. In such embodiments, the low pressure pump can “step up” the pressure of the resin-cement composite composition before it reaches the high pressure pump.

In some embodiments, the systems or apparatuses described herein can further include a mixing tank that is upstream of the pump and in which the resin-cement composite composition is formulated. In various embodiments, the pump (e.g., a low pressure pump, a high pressure pump, or a combination thereof) can convey the resin-cement composite composition from the mixing tank or other source of the resin-cement composite composition to the tubular. In other embodiments, however, the resin-cement composite composition can be formulated offsite and transported to a worksite, in which case the resin-cement composite composition can be introduced to the tubular via the pump directly from its shipping container (e.g., a truck, a railcar, a barge, or the like) or from a transport pipeline. In either case, the resin-cement composite composition can be drawn into the pump, elevated to an appropriate pressure, and then introduced into the tubular for delivery to the subterranean formation.

FIG. 1 shows an illustrative schematic of systems and apparatuses that can deliver embodiments of the resin-cement composite compositions of the present invention to a subterranean location, according to one or more embodiments. It should be noted that while FIG. 1 generally depicts a land-based system or apparatus, it is to be recognized that like systems and apparatuses can be operated in subsea locations as well. Embodiments of the present invention can have a different scale than that depicted in FIG. 1 . As depicted in FIG. 1 , system or apparatus 1 can include mixing tank 10, in which an embodiment of the resin-cement composite composition can be formulated. The resin-cement composite composition can be conveyed via line 12 to wellhead 14, where the resin-cement composite composition enters tubular 16, with tubular 16 extending from wellhead 14 into subterranean formation 18. Upon being ejected from tubular 16, the resin-cement composite composition can subsequently penetrate into subterranean formation 18. Pump 20 can be configured to raise the pressure of the resin-cement composite composition to a desired degree before its introduction into tubular 16. It is to be recognized that system or apparatus 1 is merely exemplary in nature and various additional components can be present that have not necessarily been depicted in FIG. 1 in the interest of clarity. In some examples, additional components that can be present include supply hoppers, valves, condensers, adapters, joints, gauges, sensors, compressors, pressure controllers, pressure sensors, flow rate controllers, flow rate sensors, temperature sensors, and the like.

Although not depicted in FIG. 1 , at least part of the resin-cement composite composition can, in some embodiments, flow back to wellhead 14 and exit subterranean formation 18. In some embodiments, the resin-cement composite composition that has flowed back to wellhead 14 can subsequently be recovered, and in some examples reformulated, and recirculated to subterranean formation 18.

It is also to be recognized that the disclosed resin-cement composite composition can also directly or indirectly affect the various downhole or subterranean equipment and tools that can come into contact with the resin-cement composite composition during operation. Such equipment and tools can include wellbore casing, wellbore liner, completion string, insert strings, drill string, coiled tubing, slickline, wireline, drill pipe, drill collars, mud motors, downhole motors and/or pumps, surface-mounted motors and/or pumps, centralizers, turbolizers, scratchers, floats (e.g., shoes, collars, valves, and the like), logging tools and related telemetry equipment, actuators (e.g., electromechanical devices, hydromechanical devices, and the like), sliding sleeves, production sleeves, plugs, screens, filters, flow control devices (e.g., inflow control devices, autonomous inflow control devices, outflow control devices, and the like), couplings (e.g., electro-hydraulic wet connect, dry connect, inductive coupler, and the like), control lines (e.g., electrical, fiber optic, hydraulic, and the like), surveillance lines, drill bits and reamers, sensors or distributed sensors, downhole heat exchangers, valves and corresponding actuation devices, tool seals, packers, cement plugs, bridge plugs, and other wellbore isolation devices or components, and the like. Any of these components can be included in the systems and apparatuses generally described above and depicted in FIG. 1 .

Various embodiments provide a resin-cement composite composition for treatment of a subterranean formation. The resin-cement composite composition can be any suitable resin-cement composite composition that can be used to perform an embodiment of the method for treatment of a subterranean formation described herein. For example, the resin-cement composite composition can include a resin, a cement, and a substituted or unsubstituted poly(alkylamine) compatibilizer. In some embodiments, the resin-cement composite composition can include about 20 wt % to about 80 wt % of a curable epoxide resin, about 20 wt % to about 80 wt % of a cement, and about 1 wt % to about 15 wt % of a polyethyleneimine compatibilizer. Various embodiments provide a cured product of a resin-cement composite composition described herein.

In some embodiments, the composition further includes a downhole fluid. The downhole fluid can be any suitable downhole fluid. In some embodiments, the downhole fluid is a cement fluid or a fracturing fluid.

EXAMPLES

Various embodiments of the present invention can be better understood by reference to the following Examples which are offered by way of illustration. The present invention is not limited to the Examples given herein.

Example 1. Preparation of Samples

A 33% active (i.e., 33% (w/w) polyethyleneimine in water) hyperbranched polyethyleneimine was added to a standard cement blend of 14 pounds per gallon (ppg). The polyethyleneimine was added as an aqueous solution by weight of cement (BWOC) to the cement mixture and water content was adjusted accordingly based on a 33% activity (e.g., to provide 33 wt % solids and 67 wt % water in the final blend). Throughout these Examples, a blend that is indicated as including a particular 10 wt % or 30 wt % of PEI solution includes 10 wt % or 30 wt % of the aqueous 33% active PEI solution.

Example 2. Settling and Rheological Viability of Samples

Each of the samples from Example 1 was mixed and tested individually for settling and rheological viability. Each of the formulations showed minimal settling when poured into cylinders and cut into sections for measurement of density in accordance with Archimedes' Principle (e.g., the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces). To measure the density using Archimedes' Principle, the cylinder was cut into disks from the top, middle, and bottom. The disks are then measured to determined their weight and also suspended in water to measure the volume change via displacement. All formulations showed positive viability for mixing at room temperature except for the Cement+30% PEI solution blend which read 300+ cP at 200 rpm using the FANN® yield stress adapter (FYSA) attachment.

Example 3. Preparation of Resin+Cement Samples

After initial testing, each blend was mixed with resin in equal parts by volume, using a standard resin blend of 9 pounds per gallon (ppg) with the resin composition indicated in Table 2.

Each cement-resin composite was tested for rheological viability. All mixtures tested showed positive rheological results including the resin+30% PEI solution in cement mixture. Addition of the resin to cement in all cases caused a decrease in the overall rheological properties of each mixture.

Example 4. Preparation of Cured Samples

The cement-resin composites of Example 3 were then poured into cylinders and allowed to cure for 48 hours. After curing, the composites were tested for stability (e.g., cut into sections for measurement of density in accordance with Archimedes' Principle, as described in Example 2), tensile strength, and compressive strength. None of the samples showed evidence of settling as each density showed ≤0.5 ppg of settling across each sample (e.g., the top, middle, and bottom disks cut from the cylinder had approximately the same density). The overall density of the composite mixtures was around 12 ppg.

Example 5. Testing of Tensile Strength of Cured Samples

Tensile strengths of the cured samples from Example 4 were measured, with results illustrated in FIG. 2 . It was observed that the addition of the PEI to cement caused minor changes in strength depending on the percent added. As part of a composite mixture, increase of the concentration of PEI caused a direct increase in the tensile strength measure almost doubling with each increase in concentration (10% and 30%) over a blend of cement and resin. Non-uniformity was present in the 50:50 cement+resin blend, but the edges were suitable for Brazilian tensile testing. Brazilian tensile testing was performed in accordance with ASTM D3967-08, by taking a 2″ diameter by 4″ length cylinder and cutting it into four separate 1″-length samples. The samples were turned on their side and placed between the platens of a servohydraulic load frame suitable for evaluation of mechanical properties and crushed at a load rate of 0.0001 inch/second.

Example 6. Testing of Compressive Strength of Cured Samples

Compressive strengths of the cured samples from Example 4 were measured at 48 hours after curing, with results illustrated in FIG. 3 . In normal cement blends, concentration of PEI caused minor changes in compressive strengths. When added into composites, however, increase in the concentration of PEI caused a decrease in compressive strength measurements. The cement+resin (50:50) composite was not tested because it did not mix well and was not possible to properly prepare for mechanical properties testing; both nonuniformity of the composite mixture and inability to effectively surface the sample edges rendered samples from this mixture not suitable for testing due to the possibility of significant point loading affecting compressive strength values.

The nonuniformity described in the cement+resin (50:50) sample for compressive strength was noticeable in all mixtures of this specific composite. As PEI was increased in concentration, uniformity of the samples became more pronounced, as illustrated by photographs of cross-sections of the cured samples from Example 4 shown in FIGS. 4A-C. The increase in uniformity is visible as a decrease of apparent graininess.

Uniformity of composites based on an increase in PEI concentration was also evident at the microscopic level. A scanning electron microscope image at 500 μm magnification of a cross-section of the cured sample of 30% PEI solution in cement+resin (50:50) blend from Example 4 is shown in FIG. 5 , clearly showing an increase of resin dispersal at 30% PEI solution concentration.

Example 7. Evaluation of Strength Development Over Time

To evaluate strength development over time, a blend of the 30% PEI solution in cement and the 30% PEI solution in cement+resin (50:50) composite from Example 3 were mixed and cured for 7 days. After the 7 day curing period, cement cylinders were prepared and crushed in order to obtain compressive strengths, with results illustrated in FIG. 6 . FIG. 6 contrasts the compressive strengths of the 7 day cured samples with the 48 hour cured samples from Example 4. Significant increases in strength were realized for both the neat and composite mixtures. Specifically, for the 30% composite mixture, an increase of roughly 1300 psi of compressive strength was ob served.

For comparison, two samples (a blend of the 30% PEI solution in cement and the 30% PEI solution in cement+resin (50:50) composite) were mixed and cured for 24 hours at 150° F. to observe how the mixtures behave at elevated temperatures, with photographs of cross-sections of the cured samples shown in FIGS. 7A-B. Even at elevated temperatures, it was observed that PEI successfully compatibilized the mixture of cement and resin.
